Situation: When install SCOM Agent on an untrusted computer, you may receive these events:
Log Name: Operations Manager
Source: OpsMgr Connector
Event ID: 20070
Description: The OpsMgr Connector connected to FQND, but the connection was closed immediately after authentication occurred. The most likely cause of this error is that the agent is not authorized to communicate with the server, or the server has not received configuration. Check the event log on the server for the presence of 20000 events, indicating that agents which are not approved are attempting to connect.
Event ID: 21016
Description: OpsMgr was unable to set up a communications channel to FQDN and there are no failover hosts. Communication will resume when FQDN is available and communication from this computer is allowed.
Troubleshooting: If you just imported CA and untrusted client certificates on the untrusted computer, restart al SCOM service on SCOM Server. That should fix the problem and the Event Viewer will show Event ID: 21019
Description:
OpsMgr has returned to communicating with it’s primary host FQDN.
